Note that suggestions for discontinuing isolation in individuals identified to be contaminated with SARS-CoV-2 might, in some circumstances, seem to battle with suggestions on when to discontinue quarantine for individuals identified to have been uncovered to SARS-CoV-2. CDC recommends 14 days of quarantine after publicity primarily based on the time it takes to develop sickness if contaminated. Thus, it’s potential that an individual identified to be contaminated might go away isolation sooner than an individual who’s quarantined due to the risk they’re contaminated.
These suggestions will stop most, however can not stop all, situations of secondary unfold. The greatest accessible proof means that recovered individuals can proceed to shed detectable SARS-CoV-2 RNA in higher respiratory specimens for as much as three months after sickness onset, albeit at concentrations significantly decrease than throughout sickness, in ranges the place replication-competent virus has not been reliably recovered and infectiousness is unlikely. Studies haven’t discovered proof that clinically recovered individuals with persistence of viral RNA have transmitted SARS-CoV-2 to others.
